Physiology

Weezing is a masculine Poison GasPokémon. He is a two-headed, purple Pokémon. They often have gases around them because they are so toxic. The biggest head has a skull and crossbones on his chest. His mid-sized head only has a circle. Apparently, they can also have three heads according to the DPP Pokédex, possibly a deformed conjoined circle between the two.

Pokédex entries

Where two kinds of poison gases meet, two Koffings can fuse into a Weezing over many years.

Yellow

It lives and grows by absorbing dust, germs, and poison gases that are contained in toxic waste and garbage.

Gold

If one of the two Koffings inflates, the other one deflates. It constantly mixes its poisonous gases.

Silver

Top-grade perfume is made using its internal poison gases by diluting them to the highest level.

Crystal

When it inhales poisonous gases from garbage, its body expands, and its insides smell much worse.

Ruby

Sapphire

Weezing alternately shrinks and inflates its twin bodies to mix together toxic gases inside. The more the gases are mixed, the more powerful the toxins become. The Pokémon also becomes more putrid.

Emerald

While two Koffing are said to fuse into Weezing the anime and games simply have a single Koffing evolve into Weezing.

Weezing and its pre-evolution Koffing were originally going to become a part Fire type Alolan Form in Sun and Moon.

Origin

Weezing is based on air pollution and smog. Appeearance-wise it resembles a cloud or a naval mine. The tumor-like growth of its second head may be a reference to how pollution can cause cancer and mutations.
